LEAD AMR Audio Codec

The LEAD AMR Codec is a DirectShow filter for compressing audio data using AMR speech compression. The AMR speech coder consists of the multi-rate speech coder, a source controlled rate scheme including a voice activity detector and a comfort noise generation system, and an error concealment mechanism to combat the effects of transmission errors and lost packets.

The multi-rate speech coder is a single integrated speech codec with eight source rates from 4.75 kbps to 12.2 kbps, and a low rate background noise encoding mode. The speech coder is capable of switching its bit-rate every 20 ms speech frame upon command. These features make LEAD AMR the preferred audio compression for streaming and video conferencing.

Adaptive Multi-Rate (AMR) is an audio data compression scheme optimized for speech coding. AMR was adopted as the standard speech codec by 3GPP in October 1998.
